Sure Grip Qube Ceramic Bearings

QUBE Ceramic Bearings are the fastest and longest lasting bearings in Sure-Grip's catalog. They use the finest ceramic technology and an extra (eighth) ball to help distribute the bearing's load and improve its overall spinning efficiency. Ceramic as a material is stronger than steel, more resistant to heat and wear, and generates less overall friction. Lubricated with grease instead of oil that will help extend the life of the bearing and improve maintenance efforts.
